# Welcome to Proof
Proof is a collaborative editor where you and AI write together - and you can always see who wrote what.
## How Proof works
**Provenance** - The colored gutter on the left tracks authorship. Green = human. Purple = AI. Every character knows its author.
**Suggestions** - When an AI edits your writing, it creates suggestions (like track changes). Green underlined text is an insertion, red strikethrough is a deletion. You accept or reject each one.
**Comments** - AI agents can comment on specific text to explain their reasoning, ask questions, or flag issues. You can reply, and the conversation continues.
## Ideas to get you started
Once your agent is connected, try asking it to:
- Write a reflection on your day - what happened, what you learned
- Draft the first version of an idea you've been sitting on
- Review something you read, watched, or built recently
- Just brainstorm - riff on a topic you're curious about
